In the perennial I like a firmer mattress than my wife, long story short we have a before they had numbers, sleep number bed at home and I found a "gently used" queen size Sleep Number with a malfunctioning pump (common problem). Kind of OK, because as my wife said, what happens when boondocking and we are on solar/battery.
Solution (possible) a replacement pump made by Silverfish

which works on 12V using a wall wart.
Actual voltage out put of the wall wart is 12.2V,. On boost our solar controller puts out 14.4V and is normally 13.2V. I was wondering if anyone has gone through this exercise and knows if the pump is likely to be harmed by that higher voltage.
